What role did advanced machinery play in the ECRL track laying?

Question

Accepted Answer

Advanced machinery, specifically the CCPG-500A, was used to mechanise and complete the full ECRL track-laying alignment from Kota Bharu to Gombak.
China Communications Construction (ECRL) Sdn Bhd said the mechanised track-laying machine, the CCPG-500A, was deployed to finish the entire East Coast Rail Link (ECRL) alignment in Malaysia, which spans 519 kilometres from Kota Bharu, Kelantan to Gombak, Selangor. The company described the CCPG-500A as the first of its kind in Malaysia and linked its use to the completion of the track construction phase.
The CCPG-500A was deployed to complete the full 519 km alignment
The track-laying for the full Kota Bharu to Gombak alignment covering 519 km was completed, marking the end of the track construction phase. The company said the CCPG-500A mechanised track-laying machine was used to complete the full ECRL alignment, with the machine characterised as the first of its kind in Malaysia.
Track completion moved the project into testing and commissioning
After the full track was laid, China Communications Construction (ECRL) Sdn Bhd said the ECRL officially entered the testing and commissioning phase. The statement framed this as the construction phase of track being completed together with system installations, meaning the work shifted from laying track to commissioning activities.
Phase 4 progress ran from April 2025 to February 5, 2026
The statement highlighted that Phase 4, covering 126 km from Maran to Gombak, began in April 2025 and was completed on Feb 5, 2026, half a month ahead of schedule. With the full Kota Bharu to Gombak track alignment completed, the project’s next stage proceeded after the mechanised track-laying work across the full route.
Track laying began in December 2023 and advanced northward to Kota Bharu
Track laying officially began in December 2023, with a royal blessing from the then Yang di-Pertuan Agong, Al-Sultan Abdullah Ri’ayatuddin Al-Mustafa Billah Shah, at Kuantan Port City. The alignment progressed from KPC northward through Maran and Dungun, reaching Kota Bharu, which set up the later Phase 4 completion that concluded the full 519 km track-laying work.
